IR, incidence rate; IRR, incidence rate ratio (2015 rate/2005 rate).

*Rates are presented per 100 000/year. ^†Ethnicity comparisons were based on England figures only to be comparable with 2005 findings. Rates are presented per 100 000/year.

^aSouth‐Asian ethnicity includes only the Indian, Pakistani and Bangladeshi ethnic groups to follow those of the 2005 study methodology.

^b P values were computed by using the Z‐test with the log‐ratio of the incidence rates.
